Explanation:

(4.1357 x 10^-15) x (5.4 x 10^2) Answer must be in scientific notation

Answers

Answer:

22×10⁻¹³

Explanation:

Scientific notation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.  Thus, in given value,

(4.1357× 10⁻¹⁵) × (5.4×10²)

22×10⁻¹³

how many atoms are in CaCI2​

Answers

Answer:

4

Explanation:

bc Ca is 1 C is one L is two

CaCl₂ is an ionic compound consisting of one calcium ion and two chloride ions; a single calcium ion has a doubly positive charge while a single chloride ion has a single negative charge. So two chloride ions bonded to one calcium ion results in an electrically neutral calcium chloride compound.

In this particular case, an ion is merely an atom with a positive or negative charge. Since there are three ions that comprise CaCl₂, there are three atoms in a single unit of CaCl₂.

Do not confuse the C here for carbon and/or the I for iodine. There is no chemical element whose symbol is “L” (yet).

Explanation:

got it on edge

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.

What is an echolocation ?

Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.

(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.

Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.

Thus, option A is correct.

Explanation:

Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significant, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:

The transition metals (with the exception of Zn, Cd and Hg) are very much hard and have low volatility. Why Zn ,Cd and Hg has low melting points. (a) These have all their electrons paired. (b) These have maximum number of unpaired electrons. (c) These have very strong metallic bonding. (d) These have more metal-metal bonding.

Answers

Answer:

Zn ,Cd and Hg has low melting points because - These have all their electrons paired.

Explanation:

These have all their electrons paired -: All the electrons in the d-subshell are combined with Zn , Cd and Hg. The metallic bonds present in them are, therefore, weak. This is why they have low points of melting and bolting. therefore , this statement is true. These have maximum number of unpaired electrons. Since , these transition metals have all electrons paired , so this statement is incorrect.These have very strong metallic bonding -: Zn, Cd and Hg d-orbital are completely filled. They have poor metallic bonding and less compact packing due to their fully filled d-orbitals, so all of them are volatile in nature. Therefore, this statement is also not valid .These have more metal-metal bonding. -: Since , their metallic bond is weak , so this statement is not true .

Hence , the correct option is A (These have all their electrons paired).

For an object that has a volume of 24.5 mL and a mass of 102g, calculate the density of the object

Answers

Answer:

The answer is 4.16 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 102 g

volume = 24.5 mL

We have

[tex]density = \frac{102}{24.5} \\ = 4.163265306...[/tex]

We have the final answer as

what is the standard form of 12,341 us?

Answers

Answer:

12341 in standard form = 1.2341 × 10⁴

Explanation:

When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.

As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.

As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:

12341 in scientific notation = 1.2341 × 10⁴.

This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.

what happens to the molecules as water freezes PLS HELP THIS IS DO TODAY

Answers

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. ... Thus water expands as it freezes, and ice floats atop water.

When water molecule freezes, the water molecules have slowed down enough that their attractions fixed them into fixed positions.

What do you mean by freezing ?

The term freezing is defined as a phase transition where a liquid converted into a solid when its temperature is lowered below its freezing point.

The freezing point is the temperature at which a liquid turns solid. In the freezer, for example, water-filled ice cube trays.

Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid. It is worth noting that the molecules in ice would be vibrating.

Thus, When water freezes, the water molecules slow down to the point where their attractions arrange them into fixed positions.
