Answer:

Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.

Answer:

Groups like the Halogens, which include Chlorine and Flourine, share similar properties both behaviorally and structurally. The Periodic Table is essentially a bunch of patterns and trends and the groups (like the one with Sodium and Potassium) were grouped together because of these similarities.

3. A 0.500 g sample of nitrogen gas combines with 1.140 g of oxygen gas to form NO2. If the atomic mass of oxygen is 16.000, cal

DedPeter [7]

Answer;

= 18.24

Explanation;

The ratio of N and O in the formula NO2 IS 1:2

Mass of nitrogen gas is 0.500 g

Moles of nitrogen will be;

= 0.500/16 = 0.03125 moles

Therefore;

The moles of Oxygen from the ratio will be;

= 0.03125 × 2 = 0.0625 moles

But; 0.0625 moles is equal to 1.140 g of Oxygen

The atomic number (mass in 1 mole) will be;

= 1.140 /0.0625

= 18.24

Thus the atomic number of Oxygen from the data is 18.24

Write a net ionic equation to show how quinoline, c9h7n, behaves as a base in water.

Natalija [7]

Quinoline, $C_{9}H_{7}N$ acts a Bronsted-Lowry base as it can accept a proton, $H^{+}$ from water to form the conjugate base, $C_{9}H_{7}NH^{+}$ . This reaction can be represented as,

$C_{9}H_{7}N(aq)+H_{2}O(l) C_{9}H_{7}NH^{+}(aq)+OH^{-}(aq)$

Here in the reaction, the weak base quinoline accepts a proton $H^{+}$ from water to form the conjugate base of quinoline, $C_{9}H_{7}NH^{+}$ and hydroxide ion, $OH^{-}$

Therefore the net ionic equation to show the basic nature of quinoline in water is,

$C_{9}H_{7}N(aq)+H_{2}O(l) C_{9}H_{7}NH^{+}(aq)+OH^{-}(aq)$

A laboratory stock solution is 1.50 M NaOH. Calculate the volume of this stock solution that would be needed to prepare 300. mL

OLEGan [10]

Answer:

Option c. 40 mL

Explanation:

Dilution formula:

M Concentrated . Concentrated Volume = Diluted volume . M diluted

1.50 M . Concentrated volume = 300 mL . 0.200 M

Concentrated volume = (300 mL . 0.200 M) / 1.50 M

Concentrated volume = 40 mL

When the dilution factor is applied, it is indicated how many times a concentration is diluted to obtain a lower solute concentration, so its concentration depends on the number of solute particles and the total volume

Why does the size of the atom of elements increases down a group and decreases when you move across?

ivann1987 [24]

This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius.Atomic radius increases from top to bottom within a group.
