solid brainly please
Explanation:
a table is closley compact that is why our hand cant go through it
Balanced chemical reaction happening here is:
3Mg(s) + N₂(g) → Mg₃N₂(s)
<u>moles of product formed from each reactant:</u>
2.0 mol of N2 (g) x <u> 1 mol Mg₃N₂ </u> = <u>2 mol Mg₃N₂</u>
1 mol N2
and
8.0 mol of Mg(s) x <u> 1 mol Mg₃N₂ </u> = 2.67 mol Mg₃N₂
3 mol Mg
Since N2 is giving the least amount of product(Mg₃N₂) ie. 2 mol Mg₃N₂
N2 is the limiting reactant here and Mg is excess reactant.
Hence mole of product formed here is 2 mol Mg₃N₂
molar mass of Mg₃N₂
= 3 Mg + 2 N
= 101g/mol
mass of product(Mg₃N₂) formed
= moles x Molar mass
= 2 x 101
= 202g Mg₃N₂
<u>202g of product are formed from 2.0 mol of N2(g) and 8.0 mol of Mg(s).</u>
<u> </u> The following are indicators of chemical changes:
Change in Temperature
Change in Color
Formation of a Precipitate
Answer:
This question is asking whether the statement is TRUE OR FALSE
THE ANSWER IS TRUE
Explanation:
A concept, as rightly defined, is the general idea of an entity, which can include objects, events, animals, or people based on common features, traits, or characteristics. Hence, the CONCEPT of something refers to a a generalized idea about that particular thing.
A concept in other words is our thought about something i.e. how we conceive or think that thing to be. Concept is a phenomenon of the "MIND" since it is abstract and cannot be seen. Based on this, the definition given in the question is TRUE.
A proton is positive energy, a neutron is neutral, and an electron is negative charge. Protons and neutrons are in the nucleus of an atom and electrons are on the electron cloud.
