Luda [366]3 years ago
3 0

Answer:

khi sôi nhiệt độ của nước đạt 100oC, đến lúc này một phần nước sôi sẽ biến thành hơi nước, hơi nước sẽ đùn lên phá vỡ mặt nước và bốc hơi vào không khí, hình thành lên hiện tượng sôi của nước. Nước sôi đánh dấu mốc chuyển đổi trạng thái từ nước (thể lỏng) sang hơi nước (thể khí).

If winds blow against a mountain from the south, then on which slope would you find the least precipitation?
Aleksandr-060686 [28]

The northern slope will have the least precipitation if winds blow against a mountain from the south.

<h3>What is Slope?</h3>

This is referred to as the degree of steepness on a surface such as rocky areas etc.

When wind blows on the southern part of a mountains, it gets stuck which is why the northern slope have the least precipitation.

7. If a waste container has 87.0 mL of 0.234 M acetic acid, how many milliliters of 2.00 M sodium
Naya [18.7K]

Answer:

V_{base}=10.2mL

Explanation:

Hello.

In this case, since the neutralization of the acid requires equal number of moles of both acid and base:

n_{acid}=n_{base}

Whereas we can express it in terms of concentrations and volumes:

M_{acid}V_{acid}=M_{base}V_{base}

Thus, we can compute the volume of sodium hydroxide (base) as follows:

V_{base}=\frac{M_{acid}V_{acid}}{M_{base}} \\\\V_{base}=\frac{87.0mL*0.234M}{2.00M}\\ \\V_{base}=10.2mL

Best regards.

A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
chubhunter [2.5K]

Answer:

<h3>The answer is option D</h3>

Explanation:

To find the speed given the kinetic energy and mass we use the formula

v =  \sqrt{ \frac{2KE}{m} }  \\

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

v =  \sqrt{ \frac{2 \times 15}{2.3} }  =  \sqrt{ \frac{30}{2.3} }  \\  = 3.61157559...

We have the final answer as

<h3>3.6 m/s</h3>

Hope this helps you
