Answer: Elements are arranged from left to right and top to bottom in order of increasing atomic number.
Explanation: Order generally coincides with increasing atomic mass.
Answer:
Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY). X-linked human genetic disorders are much more common in males than in females due to the X-linked inheritance pattern.
Explanation:
Answer:
7 moles
Explanation:
The molecular formula of sodium sulfide is Na_2S
One molecule of Sodium sulfide has 2 atoms of sodium and one atom of sulfur
1 mole of Sodium sulfide has 2 moles of sodium and one mole of sulfur
so 3.5 moles of sodium sulfide will have 2× 3.5 moles of sodium atoms
i.e 2×3.5= 7 moles of sodium atom
Answer:
Sedimentary only
Explanation:
when compacting and cementing happens then a sedimentary rock can and is made!

Answer:
Q = 1379.4 J
Explanation:
Given data:
Mass of water = 22 g
Initial temperature = 18°C
Final temperature = 33°C
Heat absorbed = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Specific heat capacity of water is 4.18 J/g.
°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 33°C - 18 °C
ΔT = 15°C
Q = 522 g ×4.18 J/g.°C× 15°C
Q = 1379.4 J
