Why there is not reaction in nac2h3o2(aq)+pb(no3)2(aq)→?
BARSIC [14]
NaC2H3O2 is called sodium acetate (CH3COONa)

2CH3COONa(aq) + Pb(NO3)2(aq) -> 2NaNO3(aq) + (CH3COO)2Pb (aq)

The reaction will not occur because no products will be precipitated, like one of the reactants is in solid form

There are 43.2 g of carbon to 14.4 g of hydrogen in a sample of methane (CH4). What percent of 37.8 g of methane is carbon?
EastWind [94]

Using the law of constant proportions  which says that within the same compound, elements exist in fixed ratios. 

Therefore; we can use the ratio of total mass to the mass of carbon, to determine the amount of carbon in another sample.

Mass C / Mass CH4 = Mass C / Mass CH4

43.2 g / 57.6 g = Mass C / 37.8 g

Mass C = 37.8 g × 43.2 g / 57.6 g 

              = 28.35 g

Hence; the percentage of carbon will be; 

=(28.35/ 37.8 )× 100%

= 75 % 

Thus; 75% of 37.8 g of methane is carbon

Create a comic strip that follows the journey of energy from the sun as it travels through the humpback whale
Arisa [49]

The path of energy flow from the sun to the humpback whale is as follows:

  • Sun---> Plankton ---> Small fishes ---> Humpback whale.

<h3>What is energy?</h3>

Energy is the ability to do work.

The primary source of energy on the earth is the sun.

The energy from the sun is used by producers to produce food on which other organisms depend on.

The energy from the sun gets to the humpback whale through producers such as plankton.

The path of energy flow from the sun to the humpback whale is as follows:

  • Sun---> Plankton ---> Small fishes ---> Humpback whale.

A new grill has a mass of 30.0 kg. you put 1.5 kg of charcoal in the grill. you burn all the charcoal and the grill has a mass o
atroni [7]

The reaction for burning of charcoal or complete combustion is as follows:

C(s)+O_{2}(g)\rightarrow CO_{2}(g)

From the above balanced reaction, 1 mole of carbon releases 1 mole of CO_{2} gas.

Converting mass of charcoal into moles as follows:

n=\frac{m}{M}

Molar mass of pure carbon is 12 g/mol thus,

n=\frac{1.5\times 10^{3} g}{12 g/mol}=125mol

The same moles of CO_{2} is released. Converting these moles into mass as follows:

m=n×M

Molar mass of CO_{2} is 44 g/mol thus,

m=125mol\times 44 g/mol=5.5\times 10^{3}g

Converting mass into kg,

1g=10^{-3}kg

Thus, total mass of gas released is 5.5 kg.
