Explanation:
<h3>Here, mass = 5kg </h3><h3> acceleration = 10m/s^2</h3>
<h3>according to the question ;</h3><h3>F = m×a ( from 2nd law of motion)</h3><h3>F = 5kg × 10m/s^2</h3><h3>F = 50kgm/s^2 or NEWTON </h3>
<h3>SO THE FORCE NEEDED IS 50 NEWTON</h3>

Answer:
11.29Kj
Explanation:
1. find moles of 33.8g of water
Molar mass of H2O: 18.02g/Mol
33.8/18.02= 1.88mols
2. find energy
1.88 x 6.02= 11.29Kj
Answer:
"Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings of the reaction."
Explanation:
For a (unbalanced) reaction: NaOH +CO2-Na2CO3 + H2O, the moles of NaOH and moles of each product are formed are mathematically given as
a) Moles of NaOH =44.05
b) Moles of Na2CO3=21.0
<h3>What is the moles of NaOH and what moles of each product are formed?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2 NaOH(aq)+ CO2(g)------> Na2CO3(aq)+ H2O(l)
Therefore
Moles of CO2= 925/44
Moles of CO2=21.0
Hence
Moles of NaOH = 2 x Moles of CO2
Moles of NaOH = 2x925/44
Moles of NaOH =44.05
In conclusion
Moles of Na2CO3 925/44
Moles of Na2CO3=21.0
And
Moles of H2O= 925/44
Moles of H2O= 21.0

Answer:
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
Explanation:
Given data:
Number of moles of hydrogen react = 4.0 mol
Number of moles of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of hydrogen and ammonia from balance chemical equation.
H₂ : NH₃
3 : 2
4 : 2/3×4 = 2.67 mol
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
