Answer:
9.82 g of Mg(NO₃)₂
Explanation:
Let's determine the reaction:
2AgNO₃ + MgBr₂ → Mg(NO₃)₂ + 2AgBr
2 moles of nitrate silver reacts with MgBr₂ in order to produce 1 mol of magnesium nitrate and silver bromide.
We determine the moles of AgNO₃
22.5 g . 1mol / 169.87g = 0.132 moles
Ratio is 2:1.
2 moles of silver nitrate can produce 1 mol of magnesium nitrate
Then, our 0.132 moles may produce (0.132 . 1)/ 2 = 0.0662 moles
We convert moles to mass:
0.0662 mol . 148.3 g/ mol = 9.82 g
The process that releases energy which causes lightning is known as Glaciation
Answer:
The fractional saturation for hemoglobin is 0.86
Explanation:
The fractional saturation for hemoglobin can be calculated using the formula
Where 
is the fractional oxygen saturation
is the partial pressure of oxygen
is the partial pressure when 50% hemoglobin is saturated with oxygen
and h is the Hill coefficient
From the question,
= 40 mm Hg
= 22 mm Hg
h = 3
Putting these values into the equation, we get
Hence, the fractional saturation for hemoglobin is 0.86.
Answer: The greenhouse gases cause Earth's surface to heat up from the sunlight.
Explanation: The greenhouse gases causes the Earth's surface to warm up in the morning and at night, the surface cools down. When it cools down, that gives the heat a chance to get back into the air, but some of the heat is trapped (which is caused by the greenhouse gases). That's why, on average, Earth stays at 58 degrees Fahrenheit.
