Plants like the ones shown in the picture, that use seeds, flowers, or fruit for reproduction are A) flowering.

The picture shows flowering plants that are using seeds, flowers or fruits and they are called flowering plant .

So the answer here is A) flowering.

The answeer to this question is A flowering. Flowering plants reproduce by making seeds in flowers. Some flowers turn into fruit that will contain the seeds. Examples are grasses, oak trees, fruit trees, and tomatoes.

I hope this helps I had it for a question on a test. :)

An ideal gas in a sealed container has an initial volume of 2.80 L. At constant pressure, it is cooled to 18.00 °C, where its
Aleks04 [339]

Answer:

T_1=-91.18\°C

Explanation:

Hello there!

In this case, given the T-V variation, we understand it is possible to apply the Charles' law as shown below:

\frac{T_1}{V_1}= \frac{T_2}{V_2}

Thus, since we are interested in the initial temperature, we can solve for T1, plug in the volumes and use T2 in kelvins:

T_1= \frac{T_2V_1}{V_2}\\\\T_1= \frac{(18.00+273.15)K(1.75L)}{(2.80L)}\\\\T_1=182K-273.15\\\\T_1=-91.18\°C

Best regards!

The heat required to raise the temperature of 12g of water from 16 C to 21 C is:
NemiM [27]

Answer:

The heat required to raise the temperature of 12g of water from 16 C to 21 C is 60 cal.

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

  • Q=?
  • c= 4.186 \frac{J}{g*C}
  • m= 12 g
  • ΔT=Tfinal - Tinitial= 21 °C - 16°C= 5 °C

Replacing:

Q= 4.186 \frac{J}{g*C} *12 g *5 °C

Solving:

Q=251.16 J

Since 1 J is equal to 0.2388 cal, then the following rule of three can be applied: if 1 J is equal to 0.2388 cal, then 251.16 J to how many cal are?

cal=\frac{251.16 J * 0.2388 cal}{1 J}

cal= 59.98 ≅ 60

<u><em>The heat required to raise the temperature of 12g of water from 16 C to 21 C is 60 cal.</em></u>

What is the formula for Na+1 and SO3^-2
KATRIN_1 [288]

Answer:

Na₂SO₃

Explanation:

We can use the <em>criss-cross method</em> to work out the formula.

1. Write the <em>symbols</em> of the anion and cation.

Na¹⁺  SO₃²⁻

2. <em>Criss-cross the numbers of the charge</em>s to become the subscripts of the other ion (see image).

3. Write the formula with the <em>new subscripts</em>.

Na₂(SO₃)₁

4. Omit all subscripts <em>that are 1.</em>

The formula becomes Na₂SO₃.
