Forces can be represented by _____, called vectors, that show the direction of a force.

Please help me with this three questions

zheka24 [161]

Answer:

1. A. Thyroid Gland Function

B. detecting Blood Clots

C. Treating Cancer

2. An example would be how many are used as tracers for diagnostic purposes

3. Beneficial because it gives us ways to eleminate pests, by the sterile insect technique

Number three is kinda iffy a bit difficult to explain it may be explained better in your book.

Anabolic reactions _______ bonds, whereas catabolic reactions __________ bonds. A. decrease; increase. B. break; make C. weaken;

nexus9112 [7]

Answer:

The corrext answer is E. make; break

Explanation:

In living organisms, the metabolism is either anabolic or catabolic where anabolic metabolism is energy consuming and catabolic metabolism is eneegy releasesing. It should however be noted that anabolic reaction builds or biosynthesize new mollecular structures while catabolic reaction breaks down complex structure bonds into simple structures

The braking down of bonds in catabolic reations realeses energy to sustain the anabolic rection process for the formation of new bonds

We add a 1.20-g sample of dry ice to a 755-mL flask containing nitrogen gas at a temperature of 25.0 C and a pressure of 725mmHg

yaroslaw [1]

Answer:

Total pressure is 1396 mmHg

Explanation:

By:

PV/RT = n

It is possible to obtain the initial moles of nitrogen gas, where:

P is pressure (725 mmHg = 0,954 atm)

V is volume (0,755L)

R is gas constant (0,082atmL/molK)

T is temperature (25,0°C = 298,15 K)

Replacing:

n = 0,02946 moles of nitrogen gas.

The moles of dry ice (CO₂; molar mass= 44,01 g/mol) are:

1,20 g × (1mol/44,01g) = 0,02727 moles of dry ice.

When dry ice sublimes, total moles are:

0,02727 + 0,02946 = 0,05673 moles

With the temperature (25,0°C = 298,15 K) and volume (0,755L) it is possible to obtain total pressure, thus:

P = nRT/V

Replacing:

P = 1,837 atm × (760 mmHg/1atm) = 1396 mmHg

I hope it helps!

Which Carbon is the triple bound attached to in 6-ethyl-2-octyne?

soldi70 [24.7K]

Answer:

-second

Explanation:

6-ethyl-2-octyne is an unsaturated compound with a triple bond.

6-ethyl-2-octyne will have a triple bound attached to the second carbon. The suffix -yne suggests that compound carry a triple bond and the number "2" before suffix refers to the position of triple bond that is second carbon.

Hence, the correct option is "-second ".
