One of the ways that we will be able to distinguish between the metals given that they have the same characteristic of being shiny and light-gray, is to density difference.
It is known that a substance whose density is larger than the density of the liquid to which it is submerged, will sink in the fluid. Also, the solid whose density is smaller compared to that of the fluid will float.
In most ideal case, we may opt to prepare a solution with density of 3 g/ml. Since aluminum has density lower than 3, it will float in the fluid. The titanium will sink on it because of a density higher than or greater than 3.
It is to be noted that pure water cannot be used because its density is 1 g/ml and both metals will sink in it.
Answer:
See the answer below
Explanation:
Plants grow in many different shapes and sizes. Much of their shape depends on an internal structure that is composed of carbon-containing molecules such as cellulose and lignin. Plants that have a strong internal structure can grow larger than other plants because their structure can support their size. Plants obtain the majority of the carbon necessary for building these structural molecules from <u>carbohydrates that are synthesized during photosynthesis.</u>
<em>Plants obtain carbon to build their structures by a process known as carbon fixation or photosynthesis. During this process, inorganic carbon in the form of carbon dioxide reacts with water to produce carbohydrate. Radiant energy from the sun is required for the process to go into completion and oxygen is released as a by-product. The entire process can be summarized by the following equation:</em>
This would be classified as a chemical change.
The mass of carbon dioxide will be 238.51g
<u>Explanation:</u>
Given:
Volume, V = 81.3 L
Pressure, P = 204 kPa
P = 204000Pa
Temperature, T = 95°C
T = 95 + 273K
T = 368K
mass of CO₂, m = ?
According to the gas law:
PV = nRT
where, R is the gas constant
n is the moles
and the value of R = 8.314 X 10³ L⋅Pa⋅K⁻¹⋅mol⁻¹
n = m/w
where,
m is the mass of the substance
w is the molecular weight
and molecular weight of CO₂ is 44 g
On substituting the value we get:
Therefore, the mass of carbon dioxide will be 238.51g
