Raul needs to ensure that when users enter an order into the tblOrders, the shipping date is at least two days after the order date on the data entry. Which option should he use?
Answer:
Input Mask
Explanation:
In this scenario, the best tool for Raul to use would be an Input Mask. When dealing with Microsoft Access or any other database tool, Input Masks are a great way of validating data inputs so that they always match the desired format. In this case, Raul would need to use input mask and apply the desired format while comparing it to the order date, therefore, making sure that it is always a minimum of 2 days after before it is accepted as a valid entry in the database.
The recipe for Bananas Foster requires 35g of ethanol to be added to the pan. The ethanol starts at room temperature (25°C) and is heated to its boiling point of 78°C. How many Joules of energy are transferred from the stove burner to the ethanol to create this temperature change? Your answer should have the correct number of significant figures. Show all work.
Given: The specific heat of ethanol is 2.46 J/g°C.
Answer:
To calculate the amount of heat released we have equation, use the equation Q = mc ΔT,
where
m= 35g
c= 2.46 J/g°C
ΔT=T2-T1 = 78-25= 53°C
now Q = mcΔT
Q = 35×2.46×53
Q = 4563.3 joule
Conclusion 4563.3 Joules of energy are transferred from the stove burner to the ethanol to create this temperature change!

A solution of 12M HCl is diluted so that it goes from 550mL to a total volume of 1000mL. What is the new concentration of the solution?
Answer:
6.6M
Explanation:
C=concentration
V=Volume
C1V1=C2V2
rearrange formula to find C2
(C1V1)/V2= C2
(12M x 550mL)/1000mL= C2
6600M*mL*/1000*mL* =C2 (cancel units)
6.6M=C2

The kidneys help the body preserve water. When an animal has not had enough to drink, the kidneys signal the body to absorb water. The animal produces little urine, so it loses less water. During this process, the kidneys work in conjunction with which body system?
Answer:
This regulatory mechanism is in conjunction with the endocrine system, particularly in the posterior pituitary gland. This is related in the secretion of vasopressin or antidiuretic hormone (ADH). In the event of dehydration or extreme thirst, the body will conserve as much fluid as possible and the posterior pituitary will secrete more ADH that will signal the kidney to reabsorb more water in the collecting tubules.

Explanation:
A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations.
Answer:
The population of the long-legged birds decreases.
Explanation:
The population of the short-legged birds increases whereas the population of long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.

Mass = 22g Volume = 2cm3 What is the Density?
Answer:
11g/cm^3
Explanation:
The density of a substance can be found By
density= Mass/volume
From the question
mass = 22 g
volume = 2 cm³
22/2=11
We have the final answer as
11 g/cm³
Answer:
11g/cm^3
Explanation:
It is because the constant formula density is
Density=Mass/ Volume.
Therefore we have
Density=22g/2cm^3
Which is = 11g/cm^3

Which of the following statements is not true? a. Water is polar. b. Water stabilizes temperature. c. Water is essential for life. d. Water is the most abundant atom in Earth’s atmosphere.
Answer: d. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
Water percentage in the atmosphere is 0.001 percent only as it not the major reservoir or source of water. The water is available in the atmosphere in the form of water vapors. These water vapors when aggregate and their concentration becomes high they fall down as rain on earth so the rain is collected in water reservoirs like oceans, rivers, lakes, ponds, aquifers, and other sources of water, which are the components of hydrosphere on earth. So, hydrosphere is most abundant in water. Moreover, water is not an atom instead it is the molecule formed by the combination of two molecules of hydrogen and one molecule of oxygen.

What does thermal energy refer to?
A. The chemical energy in reactions
B. The heat transferred between objects
C. The kinetic energy of particles within a system
D. The energy obtained from the sun
SUBMIT
Answer:
c
Explanation:
Thermal Energy has been the type of energy that refers to the kinetic energy of particles contained in a system. Hence, the correct option is (C).
What is thermal energy?
Thermal energy is the energy contained within a system as a result of its temperature. Thermodynamics, a branch of chemistry, states how heat is transmitted through multiple systems and how work is done in the process by the virtue of the first law of thermodynamics.
The thermal energy speeds the movement and collision of the particles present within the system. It is found in electric heat, geothermal, coals, etc. It is due to the kinetic energy that allows the movement of the particles.
Therefore, option C. the kinetic energy contained in the particles results in thermal energy.

How are organisms classified as Eukarya different from organisms classified as Archaea and Bacteria?
A)They are all multicellular.
B)They all produce their own food.
C) They all reproduce sexually.
D) They all have membrane-bound nuclei
Answer: D
Explanation: The Eukarya differ from the Archea and Bacteria in that their cells are eukaryotic, meaning they contain a membrane enclosed nucleus and other membrane enclosed organelles.
Eukarya is different from organisms classified as Archaea and Bacteria because Eukarya have membrane-bound nuclei. Therefore, option (D) is correct.
How does the classification of Eukarya differ from Archaea?The type of cell of the organism can be classified into three domains. First is the bacteria which have no nucleus present in cells. Then Archaea have no nucleus in the cells but they have a different cell wall than bacteria. Then Eukarya have a nucleus in them.
The domains of Archaea and Bacteria are both composed entirely of small, single-celled organisms but they also have differences. All are composed of prokaryotic cells, which are nucleus-less cells. T
All the cells in the Eukarya domain contain their genetic material or DNA within the nucleus. Four classes make up the Eukarya domain: Plantae, Fungi, Animalia, and Protista.
Therefore, the domain of the Eukarya is different from organisms classified as Archaea and Bacteria as Eukarya have membrane-bound nuclei.

a sample of gas at 25.0 c has a volume of 11.0 L and exerts a pressure of 660.0 mmHg. how many moles of gas are in the sample
Answer: 0.391
Explanation:
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 0.38moles of gas are in the sample. Ideal gas is a hypothetical gas.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. There is no force of attraction between the particles.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of gas sample = 660.0mmHg=0.86atm
V= volume of gas sample =11.0 L
n =number of moles of gas sample=?
T =temperature of gas =298K
R = Gas constant = 0.0821 L.atm/K.mol
Substituting all the given values, we get
0.86atm×11.0 L =n× 0.0821×298
On calculation we get
9.46=n×24.4
number of moles of sample=0.38moles
Therefore, 0.38moles of gas are in the sample.
