ΔT = 46.6 - 20
ΔT = 26.6ºC
<span>Specific heat of
water is 1.0 cal/g °C
</span>
Q = m * C * ΔT
5650 = m * 1.0 * 26.6
5650 = m * 26.6
m = 5650 / 26.6
m = 212.4 g
hope thips helps!
Answer:
Calculate the volume of dry gas at STP. 28). A 255-mL sample of nitrogen was collected over water at 21oC at a pressure of 745 mm
Explanation:
Answer:
The functional group is called an amide. This is option C.
Explanation:
We see this is a three-carbon chain (a propyl chain), that ends with a double bond to oxygen and a single bond to an amine group (NH2). If the end carbon were only bound to the NH2 group and 2 hydrogen atoms, it would be an amine. If the end carbon only had a double bond to oxygen and a single bond to hydrogen, it would be an aldehyde. However, when a terminal carbon (a carbon at the end of a chain) has both a double bond to oxygen, and a single bond to an amine (NH2), it is called an amide.
We can also discount the answer thiol right away because those have a carbon-sulfur bond, and there is no sulfur in this molecule.
