Answer:
False is your answer
The statement is false. The <ul> element is for unordered lists, while the <dl> elements along with <dt> and <dd> are used for description lists in HTML.
The statement that the grouping element, <ul>, contains the definition associated with a term from a description list is false. In HTML, the <ul> element is used to create an unordered list, typically represented by bullet points. The definitions associated with terms in a description or definition list are contained within a <dl> element. Within this <dl> element, each term is denoted by a <dt> (description term) element, and the corresponding definition is provided within a <dd> (description details) element. It's important to use these specific elements to ensure proper semantics and accessibility on the web.

A 35.65 g sample of NaOH contains 0.8910 moles of NaOH.
The mole, denoted by the sign "mol," is the volume of a system that has the same number of atoms in 0.012 kilograms of carbon-12 as there are elementary particles.
The mole, often known as mol, is a SI unit used to measure how many particles are present in a given substance. A mole is made up of 6.02214179 atoms or other fundamental building blocks like molecules.
Mass off NaOH = 39.997
given = 35.65 g of NaOH
No of moles of NaOH =35.65 g of NaOH × 1 mol NaOH /40.01 g
No of moles of NaOH = 0.8910 moles.

Answer:
0.8910 mols of NaOH in a 35.65 g sample of NaOH
Explanation:
Mass off NaOH = 39.997
given = 35.65 g of NaOH
35.65 g of NaOH * 1 mol NaOH = 0.8910, since there are 4 sig figs.
/40.01 g
Answer:
The object will not float in water because the density of the object is greater than that of water.
Explanation:
Density of object = 1.75 g/mL
Density of water = 1 g/mL
The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.
Answer:
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass

Answer : The number of oxygen atoms present on reactant side are, 4
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
Decomposition reaction : It is defined as the reaction in which the larger molecule decomposes to give two or more smaller molecules as a product.
The given balanced chemical reaction is,
From the balanced chemical reaction we conclude that, there 4 atoms of hydrogen and 2 atoms of oxygen present on both reactant side and product side.
Hence, the number of oxygen atoms present on reactant side are, 4
