Explanation:

Given :

Amount of solute - sucrose (C12H22O11) = 41 g

Amount of solvent -soda  = 355-mL

Molarity of the solution with respect to sucrose= ?

Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.

Formula to find the molarity of solution :

               Molarity =  

Amount of solvent is given in mL, let’s convert to L :

               1 L = 1000 mL

Therefore, 355 mL in L will be :

               = 0.355 L

We have the amount of solute in g, let’s calculate the number of moles first :

       Number of moles (n) =  

Molar mass of C12H22O11 = 342.29 g/mol.

Therefore, n =  

               = 0.119 moles.

Answer:

gravity

Explanation:

Gravity is an example of the force of attraction between two objects that have mass.

Answer:

The correct option is option C

Explanation:

Loss or gain of electron(s) occurs in a type of attraction known as electrovalent or ionic attraction. In this type, there is transfer (or loss) of electron(s) from a metal atom to become positively charged while a nonmetal accepts (or gains) this electron to become negatively charged.

When this does not happen, two metal atoms can become attached by sharing the same electrons through a form of attraction known as covalent bonding. Here, the two atoms share electrons (known as shared pair) together to achieve there octet configuration on the outermost shell.  

Answer:

The molecules of oxygen should be placed as reactants in the equation.

Explanation:

1:      N₂ + O₂ → 2NO

2:     2NO + O₂ → 2NO₂

complete reaction:

N₂ + 2O₂ → 2NO₂

We can not place oxygen at the side of products neither we can cancel it because, products can only be obtained at the end of the reaction but according to the equations' oxygen is not the end product of the reaction. But the addition into the reaction (Eq. 2) to make the new product.

Also, we can not cancel it because to cancel out molecules of oxygen should be present at the both sides with same amount in the stoichiometric equation.

Hence, in a balanced chemical equation, oxygen should be written as a reactant by using the correct number of moles.

Answer:

Risky behavior or risk-taking behavior is defined according to Trimpop (1994) as “any consciously, or non-consciously controlled behavior with a perceived uncertainty about its outcome, and/or about its possible benefits, or costs for the physical, economic or psycho-social well-being of oneself or others.” In addition to this broad definition, there are other definitions of risky behavior depending on the field of research. While in the economic view, risk is defined in terms of the variability of possible monetary outcomes, in the clinical literature, the risk is generally defined as exposure to possible loss or harm (Schonberg, Fox, & Poldrack, 2011). Turner et al. (2004) described risk-taking behavior further as either a socially unacceptable volitional behavior with a potentially negative outcome in which precautions are not taken, such as speeding, drinking and driving, drugs abuse, unprotected sex and so on.

Answer:

13924g/mol is the molar mass of the protein

Explanation:

What is the molar mass of the protein.

The osmotic pressure of a solution, π, is defined as:

π = c*R*T

Where π is osmotic pressure = 2.054torr* (1atm/760torr) = 2.70x10⁻³atm

c is molar concentration of the protein,

R is gas constant = 0.082atmL/molK

And T is absolute temperature = 298K

Solving the molar concentration:

c = π / RT

c = 2.70x10⁻³atm / 0.082atmL/molK*298K

c = 1.106x10⁻⁴ moles protein / L

The moles of protein in 150mL = 0.150L:

0150L * (1.106x10⁻⁴ moles protein / L) = 1.659x10⁻⁵ moles protein

The molar mass is the ratio of mass and moles:

0.231g / 1.659x10⁻⁵ moles protein =

Answer:

1. Greenhouse gas.

2. Carbon sequestration.

3. Greenhouse effect.

Explanation:

Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.

Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.

Matching the descriptions with their term respectively, we have;

1. Greenhouse gas: carbon dioxide, water vapor, methane, nitrogen oxides, and some CFCs that absorb heat and keep it in the earth's atmosphere

2. Carbon sequestration: it's a technology used to capture the carbon released from smokestacks and store it in some part of the environment to keep it out of the atmosphere. Thus, it's a process that is typically used for capturing and the long-term storage of atmospheric carbon dioxide in soil, ocean, plants and geologic formation, so as to reduce global warming or climate change.

3. Greenhouse effect: it's a term used to describe the negative role that greenhouse gases such as methane, water vapor, carbon dioxide etc., play in keeping the earth warm.

Answer:

The final temperature aluminium-water system is 24° C

Explanation:

Heat energy, H = mcθ

Where m is mass of substance, c is specific heat capacity, θ is temperature difference

Using the principle, Heat lost = Heat gained

Let the final temperature of the aluminium-water system be Tfinal

Heat lost by aluminium, H₁ = -m₁c₁(Tfinal - 40)

Heat gained by water, H₂ = m₂c₂(Tfinal -21)

Heat lost by aluminium, H = -[30 × 0.21 × (Tfinal - 40)]

H₁ = -6.3Tfinal + 252

Heat gained by water, H₂ = 50 × 1.0 × (Tfinal - 21)

H₂ = 5Tfinal - 21

Equating H₁ and H₂

-6.3Tfinal + 252 = 5 Tfinal - 21

5Tfinal + 6.3Ffinal = 252 + 21

11.3 Tfinal = 273

Tfinal = 273/11.3

Tfinal = 24° C

Therefore, the final temperature aluminium-water system is 24° C
