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>
Hope this helps you
The balanced reaction equation for the combustion of butane is as follows;
C₄H₁₀ + 13/2O₂ ---> 4CO₂ + 5H₂O
the limiting reactant in this reaction is C₄H₁₀ This means that all the butane moles are consumed and amount of product formed depends on the amount of C₄H₁₀ used up.
stoichiometry of C₄H₁₀ to H₂O is 1:5
mass of butane used - 6.97 g
number of moles - 6.97 g / 58 g/mol = 0.12 mol
then the number of water moles produced - 0.12 mol x 5 = 0.6 mol
Therefore mass of water produced - 0.6 mol x 18 g/mol = 10.8 g

Question</h2>
I think the actual question should say "What is true of most body cells except skin cells?" I found this on another source.
Answer:
B
Explanation:
A is false for all cell types. In every cell, genes are organised into chromosomes in the same way. However, the way they are expressed is different between different cells.
C - is false for all cell types - all cells contain the same chromosomes with the same genes.
D - is false. All cells contain the same chromosomes and genes, it is the expression patterns of the genes that direct cell identity.
B is true, each body cell contains the same genes and chromosomes. The only exception is the sex chromosomes, which are haploid and genetically unique. This means that when fertilisation occurs following sexual reproduction, the diploid state is restored and a genetically unique organism is created.
D he predicted 3(?) new element that we're later discovered
