Answer:

The correct answer will be option-instructions for each specific function

Explanation:

DNA is known as the genetic and heredity material of the organism which provides instructions to the cell to perform functions.

The biochemistry of DNA suggests that the arrangement of different nitrogenous bases controls different functions of the cell as they form proteins through the transcription and translation process.

Therefore, DNA controls the cell and its function by providing instructions to the organelles in the form of proteins and thus, the selected option is the correct answer.

A liquid solvent is added to a flask containing an insoluble solid. The total volume of the solid and liquid together is 93.0 mL

shutvik [7]

Answer:

Mass of solid = 189.141 gram

Explanation:

Given:

Total volume = 93 ml

Mass of liquid = 33.7 gram

Density of liquid = 0.865 g/ml

Density of solid = 3.50 g/ml

Find:

Mass of solid = ?

Computation:

Volume of liquid = Mass of liquid / Density of liquid

Volume of liquid = 33.7 / 0.865

Volume of liquid = 38.9595 ml

Volume of solid = Total volume - Volume of liquid

Volume of solid = 93 - 38.9595

Volume of solid = 54.0405 ml

Mass of solid = Volume of solid × Density of solid

Mass of solid = 54.0405 ml × 3.50 g/ml

Mass of solid = 189.141 gram

At a birthday pool party, the temperature is 28.50°C and the atmospheric pressure is 755.4 mmHg. One of the decoration helium ba

Iteru [2.4K]

Answer:

The volume of the balloon will be 5.11L

Explanation:

An excersise to solve with the Ideal Gases Law

First of all, let's convert the pressure in mmHg to atm

1 atm = 760 mmHg

760 mmHg ___ 1 atm

755.4 mmHg ____ (755.4 / 760) = 0.993 atm

922.3 mmHg ____ ( 922.3 / 760) = 1.214 atm

T° in K = 273 + °C

28.5 °C +273 = 301.5K

26.35°C + 273= 299.35K

P . V = n . R .T

First situation: 0.993atm . 6.25L = n . 0.082 . 301.5K

(0.993atm . 6.25L) / 0.082 . 301.5 = n

0.251 moles = n

Second situation:

1.214 atm . V = 0.251 moles . 0.082 . 301.5K

V = (0.251 moles . 0.082 . 301.5K) / 1.214 atm

V = 5.11L

which are correct formulas for ionic compounds? for those that are not correct, give the correct formula and justify your answer

skelet666 [1.2K]

Answer:

Ionic compounds have a metal and nonmetal.

Ionic compounds are made up of ions.

Explanation:

You did not provide any formulas for me to correct, but:

ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
ionic compounds are made up of ions. Ions are elements that have a charge (Like $Cu^{2+}$ or $O^{-}$ ). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.

EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up, they successfully cancel each other out (become neutral) and become the ionic compound NaCl.

The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.

The very last chart shows the metals and nonmetals
