Explanation:
Cause the weather made those rocks. Like volcanos and weather.
Answer:
T2 = 51.6°C
Explanation:
Given:
P1 = 1.01 atm
T1 = 25°C + 273 = 298K
P2 = 1.10 atm
T2 = ?
P1/T1 = P2/T2
Solving for T2,
T2 = (P2/P1)T1
= (1.10 atm/1.01 atm)(298K)
= 324.6 K
= 51.6°C
where Tc = Tk - 273
Answer:
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Explanation:
Chemical equation:
Na + O₂ → Na₂O
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.
Coefficient with reactant and products:
Na 4
O₂ 1
Na₂O 2
Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.
Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.
When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.
Answer:
5.83 M
Explanation:
Given data:
Volume of HBr = 125.0 mL
Molarity of HBr solution = 3.5 M
Volume of LiOH = 75.0 mL
Molarity of LiOH = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Molarity of HBr
V₁ = Volume of HBr
M₂ = Molarity of LiOH
V₂ = Volume of LiOH
Now we will put the values.
3.5 M ×125.0 mL = M₂ × 75.0 mL
437.5 M.mL = M₂ × 75.0 mL
M₂ = 437.5 M.mL / 75.0 mL
M₂ = 5.83 M
Answer: Turgor pressure can help plants move. Internal water pressure can cause a wilted stem to return to an upright position.
