Answer:
Silicon
Explanation:
The total of electrons: 2 + 2 + 6 + 2 + 2
In neutral state: #electrons = #protons = 14
so element with atomic number of 14 is silicon
Answer:
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
Explanation:
Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.
petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.
Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.
gas and oil are used to heat homes.
Answer:- A) 1 mole of Fe and 1.5 moles of 
.
Solution:- The balanced equation is:
From balanced equation, there is 1:3 mol ratio between 
and CO, From given data, 3 moles of and 1.5 moles of CO are taken for the reaction. CO is the limiting reactant as it's moles are less than the other reactant and which is also clear from the mole ratio. We could do the calculations also to support this. Let's calculate the moles of CO required to react completely with given 3 moles of .
= 9 mol CO
So, from calculations, 9 moles of CO are required to react completely with 3 moles of Iron(III)oxide but only 1.5 moles of CO are available. Hence, CO is the limiting reactant and the product moles are calculated from this as:
= 1 mol Fe
= 1.5 mol
So, the correct choice is A) 1 mole of Fe and 1.5 moles of .
Answer:
<h2>The answer is 100 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 10 kg
acceleration = 10 m/s²
We have
Force = 10 × 10
We have the final answer as
<h3>100 N</h3>
