The subatomic particle which will be attracted by a positively charged object is: Choice 3: Electrons.
By law of electricity; like charges repel while unlike charges attract.
In essence, the subatomic particle which will be attracted to a positively charged object is a negatively charged particle.
Since, protons are positively charged, neutrons have no charge, positrons are positively charged but electrons are negatively charged,
The subatomic particle which will be attracted by a positively charged object is; Electron.

True
Or False
True. In a chemical change, the same atoms are recombined into a new substances,
In a chemical change, also known as a chemical reaction, the atoms of the reactants are rearranged and recombined to form new substances with different chemical properties.
While the atoms themselves are not created or destroyed, their arrangement and bonding patterns change, resulting in the formation of new molecules or compounds. This process involves breaking and forming chemical bonds, leading to the creation of different substances with distinct properties from the original reactants.

Answer:
Explained below.
Explanation:
Formula when magnesium reacts with hydrochloric acid is given by;
Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)
So, from the equation, we can see that the gas formed is hydrogen.
This hydrogen gas is collected by a method known as water displacement.
This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
Answer:
Explanation:
We know that in 1 mole of any substances there are atoms
This number () is a constant that is known as the avogadros number
if we know how many atoms are in a mole of chromium to calculate how many there are in 11.9 moles we apply a simple rule of three
In 11.9 moles of chrome there are atoms
Answer: A) calcite
Explanation:
Hardness can be defined as the ability of the mineral to resist the scratch. It is the property to judge the hardness of the mineral. Mineralogist study this property of hardness using Mohs hardness scale.
Talc is the least hard substance after that gypsum, then calcite, fluorite, and then apatite.
The gypsum can be scratched by the calcite but the calcite cannot scratch apatite as it is softer than apatite.
