If you're wearing a yellow shirt in magenta light, what colour does the shirt look like now?

Answer:

Cows and other ruminant animals (like goats and sheep) emit methane, a potent greenhouse gas, as they digest grasses and plants. This process is called “enteric fermentation,” and it's the origin of cows' burps.

Answer:

The water is clearly close to boiling temperature when you add the ice. So, initially the ice cools the water that is near it to near 0degC. Water between about 0 and 8 degrees is more dense than hotter water, so the cold water sinks to the bottom.Jun 14, 2020

Answer:

By using the techniques of archeology.

Explanation:

Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.

Answer:

You will need to have a red flower in the top left, a pink flower in the top right and bottom left, and a white flower in the bottom right.

Explanation:

This flower appears to express color through codominance, which means that both genes express themselves. "R" is the dominant gene for red, and "r" is the recessive gene for white. When a flower has RR genotype, the phenotype will be a red flower. When a flower has an Rr genotype, the red and white genes will both be expressed and the phenotype will be pink. When a flower has an rr genotype, it lacks the red gene and will therefore be only white.

Explanation:

Answer:

228.4 kPa

Explanation:

From thw question,

PV/T = P'V'/T'..................... Equation 1

Where P = Inital pressure, T = Initial Temperature, V = Initial Volume, P' = fInal Pressure, V' = Final volume, T' = Final Temperature.

Make P' the subject of the equation

P' = PVT'/TV'...................... Equation 2

Given: P = 115 kPa, V = 15.0 dm³, T = 33°C = (33+273) K = 306 K, T' = 51.2°C = 51.2+273 = 324.2 K, V' = 8.00 dm³

Substitute these values into equation 2

P' = (115×15×324.2)/(306×8)

P' = 228.4 kPa.

Answer:

Gas and Liquids

Explanation:

To balance a chemical equation, both sides should have equal mass, or in other words both sides should have same number of atoms as to follow the conservation of mass rule.

P + O₂ = P₄O₆

LHS:

Number of Phosphorus atoms = 1 atom

Number of Oxygen atoms = 2 atoms

RHS:

Number of Phosphorous atoms = 4 atoms

Number of Oxygen atoms = 6 atoms

Also since P₄O₆ has the most number of atoms we will make the LHS equalize to P₄O₆.

Difference between Phosphorous atoms in LHS to RHS = 3

Since phosphorous is a monatomic we need 3 phosphorous atoms extra

Difference between Oxygen atoms is LHS to RHS = 4

But Oxygen is diatomic, so we need 4/2 = 2 Oxygen molecules

Now lets see if it is balanced

P + 3P + O₂ + 2O₂ -------> P₄O₆

               4P + 3O₂ ------>  P₄O₆

LHS:

Phosphorous atoms = 4 atoms

Oxygen atoms = 3 × 2 = 6 atoms

RHS:

Phosphorous atoms = 4 atoms

Oxygen atoms = 6 atoms

LHS = RHS

Therefore the balanced equation is 4P + 3O₂ =  P₄O₆

The mass of NaHCO₃ needed to produce 2.659 moles of CO₂ is 446.712 g

We'll begin by writing the balanced equation for the reaction. This can be obtained as follow:

2NaHCO₃ —> Na₂CO₃ + CO₂ + H₂O

Molar mass of NaHCO₃ = 23 + 1 + 12 + (16×3)

= 84 g/mol

Mass of NaHCO₃ from the balanced equation = 2 × 84 = 168 g

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

With the above information, we can obtain the mass of NaHCO₃ needed to produce 2.659 moles of CO₂. This can be obtained as follow:

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

Therefore,

Xg of NaHCO₃ will decompose to produce 2.659 moles of CO₂ i.e

Xg of NaHCO₃ = 168 × 2.659

Xg of NaHCO₃ = 446.712 g

Thus, 446.712 g of NaHCO₃ is needed to produce 2.659 moles of CO₂.

“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

Option D: nitrogen waste

Explanation:

Excretion.

This is removal from of waste products of chemical reactions. It involves the eliminating excess water and salts taken in with our human diet and also spent hormones

Nitrogenous waste products are the human waste products which contain nitrogen and are poisonous to the body.

The kidneys is responsible for the remove of Nitrogenous waste, water, salts, toxins, hormones e. t. c. It is the are the main principle excretory organs. They maintain the constant concentration of materials in the body.

Answer:

196 grams

because ^^^ was wrong and person in comments said it was 196 and it was right

When NaOH of 4.00 g is being added with water, the mass of water required to create 2.00% of NaOH solution by mass is 196 g.

It means that the particular amount of solute in terms of percentage is present in the solute.

Given the mass of the solute, NaOH is 4.00g

Suppose the mass of water required to add is x in g.

The mass percent of the solute is

[tex]\dfrac{2}{100} =\dfrac{4.00}{4.00 +x }[/tex]

x =196 g

Therefore, mass of water required to create 2.00% of NaOH solution by mass is 196 g.

Answer:

Atomic size decreases on going along a period from left to right because the electron enters into the same shell, therefore, attraction between nucleus and outermost electron increases and thus atomic size decreases. Valency first increases from 1 to 4 and then decreases from 4 to GO along a period from left to right.

Per cent composition of Magnesium (Mg) in Magnesium Phosphate compound ie [tex]Mg_3(PO_4)_2[/tex] is 27.74%. Hence, option C is correct.

Percent is from the Latin adverbial phrase per centum meaning “by the hundred.”

Determination of the percentage composition of Mg in Mg₃(PO₄)₂

Molar mass of Mg₃(PO₄)₂ = 262 g/mol

Mass of Mg in Mg₃(PO₄)₂ = 24×3 = 72 g

Percentage composition of Mg =?

[tex]Percentage = \frac{Mass \;of \;elements x 100}{Mass \;of \;compound}[/tex]

[tex]Percentage = \frac{72 X 100}{262}[/tex]

Answer:

1144 g of FeS

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe + S —> FeS

From the balanced equation above,

1 mole of Fe reacted to produce 1 mole of FeS.

Therefore, 13 moles of Fe will also react to produce 13 moles of FeS.

Finally, we shall determine mass of 13 moles of FeS. This can be obtained as follow:

Mole of FeS = 13 moles

Molar mass of FeS = 56 + 32

= 88 g/mol

Mass of FeS =?

Mass = mole × molar mass

Mass of FeS = 13 × 88

Mass of FeS = 1144 g

Therefore, 1144 g of FeS were obtained from the reaction.
