more photons come out of the light source?

A block has a mass of 30g and dimensions of 1.5cm by 4.8cm by 2.3 cm. Will the block float or sink in

zimovet [89]

The block will sink

Explanation:

In general, an object with a higher density than water will sink in it, and one with a lower density will float. Now, to know if the block will float or sink, the first step is to calculate the density of the block, and to do this, the volume and mass of the block are required.

Mass of the block: 30 grames

Volume of the block:

The volume of the block is not provided, but this can be found using the dimensions given.

V (Volume) = s (side) x s x s

V = 1.5 cm x 4.8 cm x 2.3 cm

V = 16.56 $cm^{3}$

Density of the block:

To find the density simply divide the mass into the volume

D (density) = M (Mass) ÷ V (Volume)

D = 30 grams ÷ 16.56 $cm^{3}$

D = 1. 811 grams/ $cm^{3}$

The density of the block is 1. 811 grams/ $cm^{3}$

Additionally, the density of the water is 1 gram/ $cm^{3}$ or 1 gram/mL. According to this, the density of the block is higher than the density of the water, and therefore this is the block sinks.

What is the main precaution to take if a gas cylinder sign is present in the lab? select one

Step2247 [10]

The main precautions to take if a gas cylinder sign is present in the lab visually check that the gas cylinder is restrained, but keep a safe distance from it. The correct option is c.

<h3>What are the precautions?</h3>

Precautions are the preventive steps that are taken to save yourself from any dangerous circumstances. These steps are always taken in doing experiments and other scientific procedures.

Here, the precautions are to check the gas cylinder.

Thus, the correct option is c, Visually check that the gas cylinder is restrained, but keep a safe distance from it.

To learn more about precautions, refer to the link:

The question is incomplete. Your most probably complete question is given below:

Remove the strap from around the gas cylinder to use it in the lab.

Open the valve on the gas cylinder periodically to release pressure.

Visually check that the gas cylinder is restrained, but keep a safe distance from it.

Test out the regulator on the gas cylinder to make sure it is working properly.

Calculate the pH of a 3.58x10^-9 M Nitric acid (a strong acid) solution

lubasha [3.4K]

Answer:

pH= 8.45

Explanation:

when working with strong accids pH = -log(Concentration)

so -log(3.58e-9) = 8.446

Please answerrrrrrrrrrrrrrrrrrrrrrrrr

nydimaria [60]

Answer: I'm in no way like an expert but I've heard water goes from an elevated area to a lower area. So it should be arrows that start at a more elevated to less elevated. Like white to brown, and orange to yellow, and stuff like that. I hope that helped? Anyway, have a lovely day!

Atoms of element X weigh 32 times more than atoms of element Y. A compound has the formula: XY2 The ratio of the mass of X to th

tamaranim1 [39]

Answer:

16:1

Explanation:

Atoms of element X weigh 32 times more than atoms of element Y. We can write this in a symbolic way.

mX = 32 mY [1]

where,

mX and mY are the masses of X and Y, respectively

A compound has the formula: XY₂, that is, in 1 molecule of XY₂ there is 1 atom of X and 2 atoms of Y. The ratio of the mass of X to the mass of Y in this compound equals:

mX/2 mY [2]

If we substitute [1] in [2], we get:

mX/2 mY = 32 mY/2 mY = 16 = 16:1
