PLEASE HELP!!!<br><br> What is the mass of one lead atom in amu?
alexandr402 [8]

Answer: 207.2

Explanation:

In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.

Give the nuclear symbol (isotope symbol) for the isotope of bromine, Br, that contains 46 neutrons per atom.
Doss [256]
Bromine has 35 protons, and in this case 46 neutrons, so 35 + 46 = 81
Therefore, the symbol is (subscript 35)(superscript 81) Br.

A beaker with water and the surrounding air are all at 24°C. After ice cubes are placed in the water, heat is transferred from:
xxTIMURxx [149]
(3) the water to the ice cubes
  This is so because the ice cubes are colder compared to their surrounding objects.
They absorb the heat from the water, cooling it, therefore vanishing(melting).

4. Balance the following chemical equation. Say what the coefficients "a"
lisabon 2012 [21]

Answer:

a = 4

b = 3

Explanation:

<u>SOLUTION :-</u>

Balance it by using 'hit & trial' method , and you'll get the answer :-

2Fe₂O + 3C → <u>4</u>Fe + <u>3</u>CO₂

⇒ a = 4 ; b = 3

<u></u>

<u>VERIFICATION :-</u>

<em>In reactant side of equation :-</em>

  • Number of atoms in Fe = 2×2 = 4
  • Number of atoms in O = 2×3 = 6
  • Number of atoms in C = 3×1 = 3

<em>In product side of equation :-</em>

  • Number of atoms in Fe = 4×1 = 4
  • Number of atoms in C = 3×1 = 3
  • Number of atoms in O = 3×2 = 6

Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
