Biotic, or living, factors can also affect an organism's ability to survive in an ecosystem. They include food availability, competition with other organisms, plant cover availability, predation, disease, parasitism, crowding, habitat fragmentation and the presence of human populations

Is food being digested physical or chemical change??

mario62 [17]

chemical. During the process of digestion, the food is broken down into smaller molecules. The salivary glands present in our mouth helps in the breakdown of the food. In this process, there is a formation of a new substance. Therefore, it is considered to be a chemical change.

Answer:

The volume will be 2600 L.

Explanation:

Initial temperature ( $T_{1}$ ) = 25°C = (25 + 273) K = 298K

Final temperature ( $T_{2}$ ) = 54°C = (54 + 273) K = 327 K

By using the combined gas law equation,

$\frac{P_{1} V_{1} }{T_{1} }$ = $\frac{P_{2} V_{2} }{T_{2} }$

or, $\frac{760* 1200}{298}$ = $\frac{380* V_{2} }{327}$

or, 3060 × 327 = 380 × $V_{2}$

or, $V_{2}$ ≈ 2600 L

Hence the volume of the balloon will be about 2600 L.

Im hvaing a hard time getting the right answer

Tanya [424]

Answer:

$V=23.9mL$

Explanation:

Hello!

In this case for the solution you are given, we first use the mass to compute the moles of CuNO3:

$n=2.49g*\frac{1mol}{125.55 g}=0.0198mol$

Next, knowing that the molarity has units of moles over liters, we can solve for volume as follows:

$M=\frac{n}{V}\\\\V=\frac{n}{M}$

By plugging in the moles and molarity, we obtain:

$V=\frac{0.0198mol}{0.830mol/L}=0.0239L$

Which in mL is:

$V=0.0239L*\frac{1000mL}{1L}\\\\V=23.9mL$

Best regards!
