For chao who is working with milk, he should adjust the temperature of the milk to have a faster reaction. for ezra who is working with rock, she must increase the surface area of the rock to increase the reaction rate, this can be done by grinding. and for mia who is working with carbon dioxide gas, she should adjust the pressure
D. The total number of valence electrons is 8 and D represents that. D also correctly uses the octet rule for N and duet rule for H.
Answer:
The resistance would be 64.10 ohms.
have a nice day my dude

Answer:
2726.85 °C
Explanation:
Given data:
Initial pressure = 565 torr
Initial temperature = 27°C
Final temperature = ?
Final pressure = 5650 torr
Solution:
Initial temperature = 27°C (27+273 = 300 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
T₂ = P₂T₁ /P₁
T₂ = 5650 torr × 300 K / 565 torr
T₂ = 1695000 torr. K /565 torr
T₂
= 3000 K
Kelvin to degree Celsius:
3000 K - 273.15 = 2726.85 °C
