How many grams are in 657 L of N2 gas at STP?
Answer:
821.25gm
Explanation:
volume = 657
no of mole = 657/22.4
mass = no of mole * molecular mass
mass = 657/22.4*28
= 821.25gm
How is a carbon atom different from a hydrogen atom?
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
The carbon atom different from a hydrogen atom, because the atomic number of hydrogen is 1 . The atomic mass number of hydrogen is also one. For the carbon atom, the atomic number is 6, and the atomic mass number of carbon is 12.
What is an atomic number ?The term atomic number is defined as the number of a chemical element in the periodic system. The elements are arranged in order of increasing number of protons in the nucleus.
The atomic number is situated at the upper left, or number of protons. In the middle is the letter symbol for the element. Atomic number is equal to the proton number or the number of protons found in the nucleus of every atom of that element.
Thus, Carbon atom is a chemical element with the symbol C and atomic number 6. Whereas hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron and its symbol is H.

A doctor's order is 0.500 g of ampicillin. The liquid suspension on hand contains 250 mg/5.0 mL. How many milliliters of the suspension are required?
The volume of the suspension required : 10 ml
Further explanationGiven
0.500 g of ampicillin
The liquid suspension concentration = 250 mg/5 mL
Required
The volume of the suspension required
Solution
The concentration of a substance can be expressed in various units such as molarity, ppm, g / L etc.
Each unit change, we must pay attention to the conversion factor
Conversion g to mg
0.5 g = 500 mg
The volume of the suspension needed :
=mass x concentration
[tex]\tt \dfrac{500~mg}{250~mg/5~ml}=500~mg\times \dfrac{5~ml}{250~mg}\\\\=10~ml[/tex]

Pls help, How is stoichiometry used to calculate amounts of substances in a chemical reaction?
Answer:
Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.
Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.

WILL GIVE BRAINIEST is C6H1005 + O2 → CO2 + H2O balanced?
Answer:
No! The balanced equation is given below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Explanation:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
The equation above is not balanced. It can be balance as illustrated below:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 at the right side. It can be balance by 6 in front of CO₂ as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on right side. It can be balance by 5 in front of H₂O as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O
There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by 6 in front of O₂ as illustrated below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Now, the equation is balanced.

Explaining Radioactive Decay
Explain the process of radioactive decay. What happens during radioactive decay, and what is the result at the end of radioactive decay?
Answer:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.
