Answer:
simple
Explanation:
A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.[1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.[2]

The nucleus of an atom is dense and positively charged. What was observed when
positively charged particles were radiated onto a gold atom during Rutherford's
experiment because of this?
O Negative charges were concentrated at the center of the atom.
N
Particles that struck the center of the atom were repelled.
Particles that struck the edges of the atom were repelled.
Positive charges were distributed all over the atom.
Answer:
The correct answer is particles that struck the center of the atom were repelled.
Explanation:
Rutherford performed an experiment which is called the gold foil experiment. In the gold foil experiment of the Rutherford, a gold foil is bombarded with the positively charged alpha particles. The bombardment of the alpha particles shows the unexpected result to Rutherford.
He thought these particles go through the gold foil but to his surprise, some particles bounced back and some deflected after colliding with foil. On the basis of these, he suggested that there is a positive charge present in the center of an atom that repelled the positive charge of alpha particles and leads to deflection and bouncing back.
Thus, the correct answer is particles that struck the center of the atom were repelled.

Magnesium carbonate decomposes on heating to form magnesium oxide and carbon dioxide as
shown.
MgCO3 → MgO + CO2
How much magnesium carbonate is needed to make 5.0g of magnesium oxide?
А
3.5g
B 4.09
C 6.5g
D 10.59
The amount of 10.5 g magnesium carbonate is needed to make 5.0g of magnesium oxide.
So, option D is correct.
Given that, Magnesium carbonate decomposes on heating to form magnesium oxide and carbon dioxide as
MgCO₃ → MgO + CO₂
Molar mass of MgCO₃ = 24 + 12 + 48 = 84 g/mole
Molar mass of MgO = 24 + 16 = 40g/mole
40 gram MgO is produced from 84 gram of MgCO₃
1 gram of MgO produced from [tex]\frac{84}{40}=2.1[/tex] gram of MgCO₃
Therefore, 5 gram of MgO produced from [tex](5*2.1=10.5gram)[/tex] of MgCO₃
Thus, option D is correct.
