Atoms are generally neutral because they have an equal amount of protons and electrons.
Yes but only if you're talking about treated apple juice with a naturally small amount of water mixed in.

Answer:</h3>
D. CH₃O₆
<h3>
Explanation:</h3>
- We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84
We are supposed to determine the empirical formula of the compound;
- We need to know what is an empirical formula;
- An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.
In this case;
The ratio of C : H : O is 14 : 42 : 84
- Note, this is not the simplest ratio.
But we can simplify further to get the simplest whole number ratio;
- Therefore, 14 : 42 : 84 is equal to 1 : 3 : 6
- Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
- Therefore, the empirical formula of the compound is CH₃O₆
Answer:
I am almost done

4.67 × 10²⁴ moles
[This is done so the equation is balanced and the reaction can occur]
[subscripts are the number of atoms, and the coefficients are the number of molecules]
______________
Since there are about 6.02 × 10²³ moles in one mol of a substance.
4.67 × 10²⁴ / 6.02 × 10²³ =
7.7547174437 mol.
Next, we must determine the grams per mole of each substance, this can be done with the periodic table.
Since hydrogen, and oxygen gas are diatomic, they will consist of two atoms each. So the atomic mass will be multiplied by 2 to get the molecular mass. Therefore H₂ will have a molecular mass of 1.00794 × 2 = 2.01588 g/mol.
Answer:- The new temperature would be 74.5 K.
Solution:- Volume is constant and according to Gay Lussac's law, "at constant volume, pressure is directly proportional to the kelvin temperature."
=25+273=298K
= ?
= 1.00 atm
= 0.250 atm
Let's plug in the values in the equation:
= 74.5K
