Answer:
atoms are in 14 moles of cadmium.
Explanation:
Cadmium is a white and silvery metal that is found in the curst of the earth.During the production process of metals such as lead, copper, zinc, cadmium is extracted
Cadmium is present in some foods and is emitted when fossil fuels like as coal and oil is used, smoking cigarettes. It is used in craft glazes, metal batteries, and coatings.
We know that 1 mole of Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.
So in 14 Grams of Cadmium, the number of atoms present is,
=>14×number atoms present in one cadmium atom
=>
=>
C. MgCl2
This structure forms a ionic bond, which are generally stronger than covalent bonds. All of the other choices are covalent.
Answer:
Her acceleration was 0.8 m/s².
Explanation:
Given data:
Final speed v₂ = 5.4 m/s
Initial speed v₁= 3.0 m/s
Initial time t₁ = 2 s
Final time t₂ = 5 s
Acceleration = ?
Solution:
acceleration = (v₂- v₁) / (t₂ - t₁)
acceleration = 5.4 - 3 / 5-2
acceleration = 2.4 / 3 = 0.8 m/s²
Answer:
2h+02=h20
Explanation:
2 in front of h on left side
2 in front of h on right side
Answer:
Increases
Explanation:
Both acids and bases can measured
using the pH or pOH scale. Both
scales provide a measure of either
the H+ concentration or the OHconcentration.
Notice that each scale shows were
acids and bases both are located.
• When acids are measured, the
pH is less than 7, but the pOH
is greater than 7.
• When bases are measured,
the pH is greater than 7, but
the pOH is less than 7.
Both scales are dependent on what
ion you are measuring
