Hehe I love Titanium!! ;) Anyways, the chemical formula of titanium (II) Oxide is TiO
Answer:
easy bro. So i also don't know.
Answer: (1) functional groups
Explanation:
Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.
Butanal is and butanone is .
and are functional isomers which have same molecular formula , similar masses and same number of carbon atoms per molecule but different functional groups attached.
Answer:
The grams of chlorophyll you need are 11,1 g
Explanation:
Osmotic pressure is the minimum pressure that you needs to be apply to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. The formula of osmotic pressure is:
π = M×R×T
Where:
M is molar concentration of dissolved species (units of mol/L).
R is ideal gas constant (0.08206 L atm mol⁻¹ K⁻¹, ).
T is the temperature on the Kelvin scale.
In the problem you have:
1,19 atm = M×0,08206 L atm mol⁻¹ K⁻¹×298K
M = 0,048 M
Thus, the grams of chlorophyll you need are:
0,048 × 0,258 L × = <em>11,1 g</em>

Answer:
- <em>Sample X</em>, contains the most heat.
Explanation:
In thermodynamics, the <em>heat content</em> of heat of a system or a substance is described by the term enthalpy.
The heat content (enthalpy) is an extensive property, meaning that it is dependent on the amount of substance.
More substance more heat energy content.
Heat content is also related with the temperature. The higher the temperature the greater the kinetic energy and the higher the heat content.
Since, sample X and sample Y are both at the same temperature of 42°C, this variable does not differentiate the heat content of such samples.
Since, the sample X has more volume than sample Y, as per the previous conclusion that the more substance the more heat energy, you can certainly asses that the former contains the most heat.
