The plant will wilt because the concentration of water in saltwater is lower than the concentration of water in the plant itself (because it is a freshwater plant). Water will diffuse out of each individual cell and the cell will crenellate (or shrivel up) causing the plant to wilt.
Answer is 55%.
Blood is fluid connective tissue that consists of two main components, plasma and formed element. Blood plasma is a clear extracellular fluid, which is a mixture of proteins, enzymes, nutrients, wastes, hormones and gases. Formed elements are made up of the blood cells (red blood cells and white blood cells) and platelets. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells.
The formed elements can be separated from plasma by centrifuge. On separation of blood components, it is evident that formed elements make up 45% of total blood volume while the plasma makes up 55% of the total volume.
<span>Sugar dissolves in water because both substances are polar substances. Water dissolves the majority of substances that are polar or ionic. The fact that sugar dissolves in water is unusual because most molecular compounds are nonpolar and are not water-soluble.
Or Number 2.</span>Sugar is a molecular compound, which means it is comprised of covalent bonds by which the atoms in the molecule share their valence electrons. This is the opposite of ionic bonding, in which atoms donate or receive electrons and change their attractive charges individually. The type of bonding atoms undergo when they react together depends on the difference in their electronegativity values. If the difference is great, they exhibit ionic bonding. If there is no difference or only a slight difference, they form covalent bonds, with the covalent bonds becoming more polar as the difference becomes greater.
In a polar covalent bond, the electrons are shared unevenly. This creates a slightly negatively charged end and a slightly positively charged end in a phenomenon known as a dipole shift. These ends allow for intermolecular interactions and give water its properties as a solvent. Polar bonds contribute to the overall polarity of the molecule, although it should be noted that not all molecules with polar bonds are completely polar. hope that helped
Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
