Balanced reaction for formation of water is ;
2H2 + O2 —> 2H2O
Stoichiometry of H2 to H20 is 2:2
1 mol of any gas occupies a volume of 22.4 L
Therefore it 22.4 L contains 1 mole
Then 1.24 L has -1/22.4 x 1.24 = 0.055 mol
Number of water moles formed = 0.055 mol
Therefore mass of water formed = 0.055 mol x 18 g/mol = 0.99 g of water is formed

Answer:

OH−(aq), and H+(aq)

Explanation:

Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;

MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)

The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.

For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.

Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.

marusya05 [52]

Answer:

B

Explanation:

Here, we wnat to get the most electronegative atom

On the periodic table, electronegativity increases across a period and decrease down the group

The elements listed are in the same group

Boron is the first member of the group

Boron is the most electronegative atom in the group

How are natural polymers and synthetic polymers similar?
Anna [14]

Answer: C) Both are made up of monomers that are linked by covalent bonds

Explanation: Polymers are large molecules which are formed by combination of small repeating units called as monomers.

Natural polymers are found in nature such as cellulose whereas synthetic polymers are synthesized in laboratories such as Nylon 6,6.

All the polymers, whether natural or synthetic are made up of monomers and are joined by covalent bonds.

Arden is making a pros and cons list about genetic engineering for a debate at school. Which part of her list is incorrect?
Soloha48 [4]

Answer:

The part of Arden's list that seems to be wrong is that genetic engineering can create organisms that survive in different environments (Pro 2).

Explanation:

Genetic engineering is a branch of genetics that introduces the use of technology to modify a living organism by introducing modified DNA into its original genome in order to improve its characteristics

The organisms subjected to changes by genetic engineering are called genetically modified organisms or GMOs, and can be stronger, longer-lived, more productive, or resistant to disease.

<em>Making a species resistant to any environment could cause it to develop in places where it could not live before, affecting the natural balance of an ecosystem to which it previously did not belong, so Pro 2 on Arden's list does not seem to be entirely beneficia</em>l.
