Answer:
2, 1, 1, 4.
Explanation:
Hello there!
In this case, for the given chemical reaction:

We can see how there is one SO4 on the left and two on the right, thus, we add a 2 in front of H2SO4:

Next, since there are 8 atoms of hydrogen on the left and two on the right, we add a 4 in front of H2O to obtain:

Which is now balanced so the coefficients 2, 1, 1, 4.
Best regards!
B is correct
salt lowers the freezing point of water (colligative property) by lowering the interaction and intermolecular forces between water molecules
The reaction: 2H2(g) + O2(g) → 2H2O(g), can be interpreted as: a. 2 moles of hydrogen gas reacts with 1 mole of oxygen gas to produce 2 moles of water.
The branch of chemist is a substance of science and pysical is the land science such as a desert of a forest those are chemist and physical science have a good day :)
Answer:
16 N
Explanation:
The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.
We have,
Input force = 8 N
Input arm distance = 6 m
Output arm distance = 3 m
We need to find the resulting output force. So,

So, the resulting output force is 16 N.
