Answer:

this is an example

Explanation:

Yes, the balloon will burst at room temperature.

As we know that, 480 x 7/8 = 420 is the maximum Stretching capacity of the balloon.

b) V. / T. = V/T

Where

V = 480 ml and T. = 5 C(278 K)

And T= 30 C( 303 K)

V = V.T/T.

V = 480 x 303/278

V = 523.1 ml

b)V./V=T./T ?

Where

V = 480 ml and

T = 5 C (278 K)?

And V = 420 ml

T=T.V./V

=278 x 480/420

= 317.17 k

Therefore the balloon will burst at the temperature of 317.17 k

The temperature of 0.5 kg of water is 303 K. It is cooled to 278 K by keeping it in a refrigerator. what is the time taken by water to reach 278 K if 87.5 J of heat is given out in each second? ( specific heat capacity of water is 4200 J/kg K )

Ions are atoms with a charge other than zero. In a neutral atom, the number of protons (positively charged particles) in the nucleus equals the number of electrons orbiting the nucleus.
Atoms can gain or lose electrons (not protons) resulting in a net charge other than zero. Atoms which lose electrons (usually metals) become positively charges, and atoms which gain electrons (usually nonmetals) become negatively charged.

A student used 1.168g of an unknown weak acid and titrated it against 28.75 mL of 0.105M NaOH to reach the equivalence point. Wh

Vaselesa [24]

Answer:

The molar mass of the unknown acid is 386.8 g/mol

Explanation:

Step 1: Data given

Mass of the weak acid = 1.168 grams

volume of NaOH = 28.75 mL = 0.02875 L

Molarity of NaOH = 0.105 M

Since we only know 1 equivalence point, we suppose the acid is monoprotic

Step 2: Calculate moles NaOH

Moles NaOH = molarity NaOH * volume NaOH

Moles NaOH = 0.105 M * 0.02875 L

Moles NaOH = 0.00302 moles

We need 0.00302 moles of weak acid to neutralize the NaOH

Step 3: Calculate molar mass of weak acid

Molar mass = mass / moles

Molar mass = 1.168 grams / 0.00302 moles

Molar mass = 386.8 g/mol

The molar mass of the unknown acid is 386.8 g/mol

What is the type of mutation represented by the amino acid sequence below?

Ilia_Sergeevich [38]

Answer:

Substitution mutation

Explanation:

A substitution mutation is a type of mutation in which one or more nucleotide base is replaced by another in a sequence. This will result in the replacement of one or more amino acid in the amino acid sequence.

This is the case in this question where the original amino acid sequence was given as: Leucine – Alanine – Glycine – Leucine. After mutation, the following mutated sequence was produced: Leucine – Alanine – Valine – Leucine.

As illustrated above, one would notice that there is replacement of GLYCINE amino acid by VALINE in the mutated sequence, hence, it is an example of SUBSTITUTION MUTATION.
