Any shipment of peanuts that contains more than 25 ppb of this dangerous fungus is rejected. A company receives 24 t of peanuts to make peanut butter. What is the maximum mass, in g, of fungus that is allowed? Hint 1 t = 1000 kg.
Answer:
0.60g of the fungus can be allowed
Explanation:
The maximum concentration of the fungus that can be allowed is 25 ppb, that is 25mg/t.
As the peanuts are 24t, the mass of fungus that can be allowed is:
24t * (25mg/t) = 600mg of the fungus can be allowed. In grams are:
600mg * (1g/1000mg) =
0.60g of the fungus can be allowedAnswer:
0.5g of toxin
Explanation:
ppb = mass of solute/ mass of solution x 10^9
ppb = mass of fungus/ mass of peanuts x 10^9
25ppb = (x/2 x 10^7g) x 10^9
x = (25)(2 x 10^7g)/ 10^9
x = 0.5g of toxin
x represented the unknown mass of solute (fungus), in which we solved for. We already knew we were using the ppb formula, which is mass of solute/ mass of solution x 10^9, because the question mentions that there are 25ppb of peanuts in the shipments. In the calculations, you can see that I substituted the mass of peanuts with 2 x 10^7g. I did this because the question mentions that there are 20t of peanuts and since each t = 1000kg, I multiped 20 x 1000 to get 20 000kg. In my formula for ppb, I know that I have to use grams of solution, not kilograms. Knowing this, we follow the formula for ppb and substitute our known values and solving for unknown values.

why water molecules remain associated in liquid water
Answer:
Answer: They are attracted to each other due to their electrostatic attraction. All that means is the hydrogen atom is positively charged, while the oxygen atom is negatively charged. ... The hydrogen of one water molecule will bond to the oxygen atom of another molecule.

what is water
a. a universal solvent
b. something you can drink
c.a liquid
Answer:
FIRST OPTION WHICH IS A: UNIVERSAL SOLVENT
Explanation:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

13.8g element consist 4.6 ×10^22 atoms what is atomic mass of element?
We know that,
4.6 x $ \sf{10^{22}}$ atoms of an element weigh 13.8g.Thus,
The atoms of $ \sf{ 6.02 \times 10^{13}}$ will weigh;
[tex] = \sf{\frac{13.8 \times 6.02 \times {10}^{23} }{4.6 \times {10}^{22} } } \\ [/tex]
[tex] = \sf{180.6 \: g \: \: (molar \: mass)}[/tex]
Hence, the molar mass (atomic mass) will be 180.6 g.Find the number of moles of sodium hydroxide in 25cm3 solution of concentration 0,1 mol/dm3
Answer:
0.0025 moles
Explanation:
25cm^3 = 25/1000 dm^3
Conc = mol/dm^3
Mol = conc * dm^3
Mol = 0.1 * 25/1000
Is there law in the United States? Why are black people killed at random by police?
The sum of the kinetic energies and potential energies of all of the molecules
in a substance is called the energy of the substance?
Answer:
The correct answer is - internal energy.
Explanation:
The movements of the particles are continuous inside In any substance/object, within random directions and with random speeds which are termed as Brownian motion.
Due to these movements, these substances have some kinetic energy and the interaction between particles takes place due to the presence of electrostatic intermolecular forces, this leads to having some potential energy. The sum of the kinetic energies and potential energies of the particles in a substance is called internal energy it is internal to the confines of the substance.

Answer in detail?? What precautions would you take to protect yourself from an earthquake, when you are at home and when you are outdoors?
Answer:
If you're indoors, stay inside. If you're outside, stay outside. If you're indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors.
Answer
Protect your head and neck with a large book, a pillow, or your arms. The goal is to prevent injuries from falling down or from objects that might fall or be thrown at you.If you are able, seek shelter under a sturdy table or desk. Stay away from outer walls, windows, fireplaces, and hanging objects.If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows.If you are outside, go to an open area away from trees, telephone poles, and buildings, and stay there.The graph shows the change in concentration of one of the species in the reaction

Classify EACH possible hypothesis about a medical aloe Vera plant as falsifiable or non-falsifiable
A) Aloe Vera gel is the best natural skin moisturizer.
B) Aloe Vera gel can heal wounds by boosting cell renewal.
C) Aloe Vera juice tastes better than carrot juice.
D) Drinking aloe juice can reduce the risk of lung cancer.
Answer:
The correct answer is -
FALSIFIABLE:
Aloe vera gel can heal wounds by boosting cell renewal.
Drinking aloe juice can reduce the risk of lung cancer.
NON-FALSIFIABLE:
Aloe vera gel is the best natural skin moisturizer.
Aloe vera juice tastes better than carrot juice.
Explanation:
Falsifiable is the ability or chances of any hypothesis, claim or statement to be proved wrong. In such a hypothesis, it is possible to carry an experimental observation that disproves the idea in claim or question.
In the given examples
Aloe vera gel can heal wounds by boosting cell renewal.
Drinking aloe juice can reduce the risk of lung cancer.
There is no observation in the favor of the claim so there more likely to be falsifiable whereas, Aloe vera gel is the best natural skin moisturizer.
Aloe vera juice tastes better than carrot juice are more non-falsifiable as these are based on personal choice or experimental observation.
Answer:
FALSIFIABLE IS *DOWNARROW
Aloe vera gel can heal wounds by boosting cell renewal.
Drinking aloe juice can reduce the risk of lung cancer.
NON-FALSIFIABLE IS *DOWNARROW*

Question:
Nearly the entire world uses the metric system for their measurements. The US is one in of three countries that does not use metric. Would you support changing school curriculum to teach the metric system as the primary measurement system in the US? Why or why not.
(It must be 3-5 sentences long please)
Answer:
I would
Explanation:
I would support the change to the metric system only because it allows children to understand smaller forms of units and measurements. Also, it will allow people in the math and science fields to broaden their knowledge of equations and formulas. Meaning that the scientist and mathematicians will be able to solve more problems in the world right now. Overall, the education system for the children of the United States would benefit from the change in the measurement system.
What must scientists look for in their experiment or their data to make sure it is accurate?
