This reaction would produce salt and water- Sodium Sulphate and Water.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
by radiation from the Earth's surface
Explanation:
Let us take the volume of block is x.
Since, the block is floating this means that it is in equilibrium. Formula to calculate net force will be as follows.

Also, buoyancy force
= (volume submerged in water × density of water) + (volume in oil × density of oil)
=
=
g
As, W = V × density of graphite × g
It is given that density of graphite is
or 2160
.
So, W = 2160 V g
= (0.592 V \rho + 408 V) g - 2160 V g = 0
= 1752
= 2959.46
or 2.959
is the density of oil.
It is given that mass of flask is 124.8 g.
Mass of 35.3
oil =
104.7 g
Hence, in second weighing total mass will be calculated as follows.
(124.8 + 104.7) g
= 229.27 g
Thus, we can conclude that in the second weighing mass is 229.27 g.
Answer:
the answer is C) sharing
Explanation:
positive ions & negative ions form when atom s lose or gain electrons. Covalent bonds form when atoms share electrons.Metallic bonds form by the attraction of metal ions and the electrons around them. Covalent compounds form when atoms of elements share electrons.
