A researcher studying the nutritional value of a new candy places a 4.90 g sample of the candy inside a bomb calorimeter and com
snow_lady [41]

Answer:

449730.879 cal/g

Explanation:

Given data:

Mass of sample = 4.9 g

Change in temperature  = 2.08 °C  (275.23 k)

Heat capacity of calorimeter = 33.50 KJ . K⁻¹

Solution:

C(candy) = Q/m

Q = C (calorimeter) × ΔT

C(candy) = C (calorimeter) × ΔT / m

C(candy) =  33.50 KJ . K⁻¹ × 275.23 K / 4.90 g

C(candy) = 9220.205 KJ / 4.90 g

C(candy) =  1881.674 KJ / g

It is known that,

1 KJ /g = 239.006 cal/g

1881.674 × 239.006 = 449730.879 cal/g

How can i make babies
Studentka2010 [4]

Answer with Explanation:

Babies are formed when the sperm cell from the male testicular gonad meets with the women's egg cell (from the ovaries). This penetration causes the<em> "fertilization process." </em>This naturally occurs two weeks from the woman's last day of menstruation. The fertilization allows the egg to rapidly divide. This is followed by "implantation," a process whereby the blastocyte attaches to the woman's endometrium. <u>Around three weeks, the blastocyte is formed into an embryo. </u>This will be called fetus once the woman reaches its 8th week of pregnancy.

This is a brief process regarding your question on how babies are formed.
