Last Question what bond type is SO2.( ionic, polar covalent, nonpolar covalent, diatomic) **its the one right above the BELONGS

qwelly [4]

SO2 is a polar molecule because Oxygen gains more electrons making one side more negative than the other.

A spacecraft is traveling at a speed of 2.3 km/sec. It takes 2.5 minutes to pass a small asteroid. how wide is the asteroid (i.e

lidiya [134]

<u>Answer:</u> The spacecraft traveled 345 km during the given time.

<u>Explanation:</u>

To calculate the distance of spacecraft, we use the equation:

$\text{Velocity}=\frac{\text{Distance}{\text{Time}}$

We are given:

Velocity = 2.3 km/sec

Time = 2.5 mins = 150 sec (Conversion factor: 1 min = 60 sec)

Putting values in above equation, we get:

$\text{Distance}=(2.3km/s\times 150s)=354km$

Hence, the spacecraft traveled 345 km during the given time.

The specific heat capacity (c) of a substance is the thermal energy required

Ierofanga [76]

Temperature of the same cup of water will rise by 6 °C unless it boils.

<h3>Explanation</h3>

$Q = c\cdot m \cdot \Delta T$ .

However, neither $c$ nor $m$ is given.

Adding $Q = 125\;\text{kJ}$ to this cup of water of mass $m$ rises its temperature by $\Delta T = 1 \; \textdegree{}\text{C}$ .

In other words,

$\begin{array}{lll}Q &=& c \cdot m \cdot \Delta T\\125\;\text{kJ} &=& c \cdot m \times (1 \; \textdegree{}\text{C})\end{array}$

$c \cdot m = \dfrac{Q}{\Delta T} = \dfrac{125\; \text{kJ}}{1 \; \textdegree{}\text{C}}$ .

Both $c$ and $m$ are constant for the same cup of water unless the water boils. It's possible to reuse the value of $c \cdot m$ in the second calculation. Here's how:

$\Delta T = \dfrac{Q}{c\cdot m} = \dfrac{750 \; \text{kJ}}{\dfrac{125\;\text{kJ}}{1\;\textdegree{}\text{C}}} = \dfrac{750}{125} \; \textdegree{}\text{C}} = 6 \; \textdegree{}\text{C}}$ .

Synthetic fibers, like plastic, are derived from organic compounds. These fibers have been chemically changed by humans to last

Anarel [89]

The downside of this is that the longer lasting material is more difficult to break down.

Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.

The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.
