Answer:
<h2>10 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
![a = \frac{f}{m} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bf%7D%7Bm%7D%20%20%5C%5C%20)
m is the mass
f is the force
From the question
mass = 3.5 kg
force = 35 N
We have
![a = \frac{35}{3.5} \\ = 10](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B35%7D%7B3.5%7D%20%20%5C%5C%20%20%3D%2010)
We have the final answer as
<h3>10 m/s²</h3>

Answer:
Its a 1:1:1:1 molar ratio.
Explanation:
Element/Polyatomic Ion # on reactants side # on products side
Ag 1 1
NO3 1 1
Na 1 1
Cl 1 1
Answer:
5.25 g NaF
Step-by-step explanation:
We know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 41.99
Na₂SiO₃ + 8HF ⟶ H₂SiF₆ + 2 NaF + 3H₂O
n/mol: 8
(1) Calculate the moles of NaF
The molar ratio is 2 mol NaF/8 mol HF.
Moles of F = 0.500 mol HF × (2 mol Na₂SiO₃/8 mol HF)
Moles of Na₂SiO₃ = 0.125 mol Na₂SiO₃
(2) Calculate the mass of NaF
Mass of NaF = 0.125 mol NaF × (41.99 g Na₂SiO₃/1 mol Na₂SiO₃)
Mass of NaF = 5.25 g NaF
The Antoine's law means that the amount of substance before reaction must be equal the amount of substance after reaction
The equation h2 + cl2 ---> 2hcl correctly models this law.
