1) we can calculate the molecular weight of H₃PO₄
atomic mass  (H)=1 amu
atomic mass (P)=31 amu
atomic mass (O)=16 amu 

molecular weight (H₃PO₄)=3(1)+31+4(16)=98 amu.

1 mol (H₃PO₄)=98 g
1 mol= 6.022 * 10²³ molecules.

2) we calculate the mass of 4.00*10²³ molecules.

98 g-------------------6.022*10²³ molecules
x------------------------4.00*10²³ molecules

x=(98 g * 4.00*10²³ molecules) / 6.022*10²³ molecules≈65 g

Answer: 65 g

g Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 0.96 g of methane
galben [10]

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} CH_4=\frac{0.96g}{16g/mol}=0.06moles

\text{Moles of} O_2=\frac{6.37}{32}=0.20moles

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

According to stoichiometry :

1 mole of CH_4 require = 2 moles of O_2

Thus 0.06 moles of CH_4 will require=\frac{2}{1}\times 0.06=0.12moles  of O_2

Thus CH_4 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

As 1 moles of CH_4 give = 1 mole of CO_2

Thus 0.06 moles of CH_4 give =\frac{1}{1}\times 0.06=0.06moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=0.06moles\times 44g/mol=2.64g

Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.

4. What is the overall nuclear fusion reaction in the Sun? Briefly describe the proton–proton chain.
Pachacha [2.7K]

Nuclear fusion is the source of all energy the Sun releases into space. The Sun fuses hydrogen at a steady rate, thanks to a natural feedback process that acts as a thermostat for the Sun's interior (p-p chain). Solar energy production remains steady because the rate of nuclear fusion is very sensitive to temperature.

<h3>Nuclear fusion</h3>

When two or more atomic nuclei join, one or more new atomic nuclei and subatomic particles are created. This reaction is known as nuclear fusion (neutrons or protons). Energy is released or absorbed depending on how much mass the reactants and products have in common.

The atomic nuclei before and after the reaction had different nuclear binding energies, which is how this difference in mass developed. Active or main sequence stars, along with other high-magnitude stars, are powered by nuclear fusion, which releases enormous amounts of energy. Energy will often be released during nuclear fusion that creates atomic nuclei lighter than iron-56 or nickel-62. Both their mass and nucleon binding energy are relatively high for these elements.

BRAINLIEST ANSWER! PLEASE HELP!! An Earth-like planet is 500 light years away. Why is this an obstacle for a manned space missio
Setler79 [48]
I Would think it would be C Since Humans can't live 500 years but then yet again it is light years not regular years i think if you find how man years is 500 light years the that could help you in finding the answer
