A little aluminum boat (mass of 14.50

Chemistry
1 answer:
Valentin [98]3 years ago
5 0
When the volume is 450 cm3 so the boat will displace 450 g.

so we have  450 g - 14.5g = 435.5 left 

so to get how many pennies can be added to the boat before it sinks can be determined by:

divided the mass for the one penny:

no.of Penny = 435.5 / 2.5g

                     = 174.2 

∴ the boat will float with 174 pennies and will start to sink with 175

Empirical formula of at least four binary ionic zn2+,pb4+,br-,s2-
Tasya [4]

Four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

<h3>What are binary ionic compounds?</h3>

Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.

Now, four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

Why does knowing the mass of an object not help you identify what material the object is made from?
jeka57 [31]
Because mass is not always the same for objects made from the same material. Just because an object has the same mass as another doesn’t mean they are the same material.

mixas84 [53]

but where Is the volume in order for us to determine the concentration. since we have moles in H+ ions

then you can say

Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0
grandymaker [24]

The given question is incomplete. The complete question is:

Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis. Determine the mass of glucose (C6H1206) produced

Answer: 60.0 g of glucose

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

a) moles of CO_2

\text{Number of moles}=\frac{88.0g}{44g/mol}=2.0moles

b) moles of H_2O

\text{Number of moles}=\frac{64.0g}{18g/mol}=3.5moles

6CO_2+6H_2O\rightarrow C_{6}H_{12}O_6+6O_2

According to stoichiometry :

6 moles of CO_2 require = 6 moles of H_2O

Thus 2.0 moles of CO_2 require=\frac{6}{6}\times 2.0=2.0moles  of H_2O

Thus CO_2 is the limiting reagent as it limits the formation of product.

As 6 moles of CO_2 give =  1 moles of glucose

Thus 2.0 moles of CO_2 give =\frac{1}{6}\times 2.0=0.33moles  of glucose

Mass of glucose = moles\times {\text {Molar mass}}=0.33moles\times 180g/mol=60g

Thus 60.0 g of glucose will be produced from 88.0 g of carbon dioxide and 64.0 g of water
