Which of the following correctly

goblinko [34]

Answer:

An element is made of one type of atom, while a compound is two or

more types of atoms combined.

Explanation:

An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.

Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.

There are over a hundred elements known to date.
Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
Examples are copper, gold, iron
The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
There are several millions of compounds known.
They are usually represented by chemical formulae.

As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

In general the human ear is most sensitive to sounds at 2500 hz. Assuming that sound moves at 330m/s what is the wavelength of s

elena-s [515]

Answer:

0.132 meters is the wavelength of sounds to which people are most sensitive.

Explanation:

Frequency of the sound human ears are most sensitive to = $\nu = 2500Hz=2500 s^{-1}$

Speed of the sound wave = S = 330 m/s

Wavelength of the sound human ears are most sensitive to = $\lambda = ?$

$\nu=\frac{S}{\lambda }$

$2500 s^{-1}=\frac{330 m/s}{\lambda }$

$\lambda =\frac{330 m/s}{2500 s^{-1}}=0.132 m$

0.132 meters is the wavelength of sounds to which people are most sensitive.

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:

Where in an equation for photosynthesis does oxygen belong?

LUCKY_DIMON [66]

Answer:

on the right side, because it is a product

Explanation:

photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.

_______________________________________________

The general standard for writing chemical reaction is that

The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
The output of chemical reaction are written on right side. They are termed as product.
Transition of reactant to product is shown by arrow.

Chemical reaction for photosynthesis is given by below equation

6CO2 + 12H2O + light ----------------> C6H12O6 + 6O2 + 6H2O

We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.

As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.

Thus, of the options given below for

In an equation for photosynthesis does oxygen belong

on the right side, because it is a product
