7. What is the prefix value for 100X?
Lilit [14]

Answer:

hecto-

Explanation:

The prefix value of 100 is hecto therefore 100X can be called hecto-x.

Such prefixes as this are expressed in the order of tens. Units generally exists scientifically in multiples and submultiples form using prefixes.

For the multiples:

             10                            deca(da)

            100                           hecto(h)

            1000                        kilo(k)

         1000000                    mega(M)

         1000000000            giga(G)

When 12 grams of carbon react with 32 grams of oxygen, the compound carbon dioxide (a greenhouse gas) is formed. What is true ab
musickatia [10]

Answer:

Option C = 6 of carbon react with 16 g of oxygen.

Explanation:

In given question it is stated that 12 g  of carbon react with 32 g of oxygen to produce carbon dioxide. The other combination option c is also true because in this, the quantity of both reactant is just half from the given quantity. Which means that if 100 % product is obtained from the 12 g of carbon and 32 g of oxygen then by taking the half amount of reactant the product will be half i.e 50% .

This combination is true because the ratio of both reactant are justified.

Carbon 12g + Oxygen 32g → carbon dioxide

           C : O     1  : 2.6

Option C:

Carbon ( 12/2 =6g ) + Oxygen (32/2 = 16g) → Carbon dioxide

           C : O     1  : 2.6

Sodium chloride can be produced by the reaction of sodium metal with chlorine gas. Which is the limiting reactant if 6.70 moles
Alecsey [184]

Answer:

Chlorine gas.

Explanation:

Hello!

In this case, the undergoing chemical reaction is:

2Na+Cl_2\rightarrow 2NaCl

Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:

n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl

Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.

Best regards!
