Fossils are found in _______.

Sergio [31]

Answer:

Sedimentary rocks

Explanation: Where are fossils found? Fossils are found almost exclusively in sedimentary rocks—rocks that form when sand, silt, mud, and organic material settle out of water or air to form layers that are then compacted into rock. So the answer will be <em>Sedimentary</em> rocks.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ $RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-(-2))^2+(4-4)^2}$

⇒ $=\sqrt{(3+2)^2+(0)^2}$

⇒ $=\sqrt{25}$

⇒ $=5 \ units$

and,

⇒ $ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-3)^2+(-1-4)^2}$

⇒ $=\sqrt{0+(-5)^2}$

⇒ $=5 \ units$

Now,

The total trail length will be:

= $RS+ST$

= $5+5$

= $10 \ units$

How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?

vaieri [72.5K]

Explanation:

The given data is as follows.

$M_{1}$ = 3 M, $V_{1}$ = ?

$M_{2}$ = 10 M, $V_{2}$ = 10.0 ml

Therefore, calculate the volume of given solution as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

Now, putting the given values into the above formula as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

$3 M \times V_{1}$ = $10 M \times 10.0 ml$

$V_{1}$ = 33.3 ml

or, = 0.033 L (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

Molarity = $\frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}$

3 M = $\frac{mass}{40 g/mol \times 0.033 L}$

mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

3. Explain the difference between the greenhouse effect and global warming.

Goshia [24]

Global warming is a long-term rise in the average temperature of the Earth's climate system. And the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
