What is the chemical symbol for calcium oxide plus carbon dioxide?
Calcium oxide is CaO, and carbon dioxide is CO2.
Which Metal oxide is acidic in nature?
Metal oxide such as zinc oxide (ZnO) or aluminum oxide (Al2O3) are considered acidic in nature when dissolved in water because they produce acidic solutions due to the presence of metal cations and oxide anions.
What is a soft heavy metal whose compounds is poisonous?
Lead is a soft heavy metal that is poisonous when ingested or inhaled. Its compounds, such as lead oxide and lead acetate, can be harmful to the environment and human health. Lead poisoning can cause a range of symptoms, including abdominal pain, neurological issues, and developmental delays in children.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.

A metal forms two oxidesThe higher oxide contains 80 percent metal 0.72g of lower oxide gave 0.8g of the higher oxide when oxidised Show that the data illustrates the law of multiple proportions?
In higher oxide Metal = 80% Oxygen = (100-80)% = 20% Therefore, we can say that 4 parts of metal combines with 1 part of oxygen. Now, 0.72 g of lower oxide on oxidation gives 0.8 g of higher oxide. It can be assumed that the mass percent of metal in 0.8 g is same as that of 0.72 g of lower oxide. So, Mass of metal in higher oxide = (80/100) x 0.8 g = 0.64 g If in 0.8 g of higher oxide 0.64 g is metal then mass of oxygen present in higher oxide will be (0.8 - 0.64) g = 0.16 g Since, lower oxide contains the same mass of metal as that of higher oxide, we need to calculate the mass of oxygen in lower oxide. Mass of oxygen in lower oxide = (0.72-0.64) g = 0.08 g According to Law to multiple proportions if two elements combine with each other to form two different compounds then the ratio of masses of that element which combines with the other element whose mass is fixed in both the compounds, will be in small whole numbers. Now, in the given problem the mass of metal in both the oxide is fixed so, for the data to illustrate the law of multiple proportion the ratio of mass of oxygen in both the oxides should be in whole numbers. Now, mass of oxygen in higher oxide : mass of oxygen in lower oxide = 0.16 : 0.08 = 2 : 1. Therefore, it can be said that the given data depicts law of multiple proportion.
Is Tin a semi-metal?
"Very malleable silver white metal that forms a protective oxide film on its surface that prevents it from reacting with oxygen." http://environmentalchemistry.com/yogi/periodic/Sn.html#Physical
What are polar capacitors?
All electrolytic capacitors (e-caps) are polarized capacitors whose anode electrode (+) are made of a special metal on which an insulating oxide layer originates by anodization (forming), which acts as the dielectric of the electrolytic capacitor.
Which metal which food is made?
iron is the metal whose food is made
What element is a soft valuable metal whose purity is measured in carats?
Gold is a soft valuable metal whose purity is measured in carats.
What determines the value of metal?
Metal value is determined by the purity of the metal. It is a commodity whose price depends on supply and demand.
What is a soft heavy metal whose compounds is poisonous?
Lead is a soft heavy metal that is poisonous when ingested or inhaled. Its compounds, such as lead oxide and lead acetate, can be harmful to the environment and human health. Lead poisoning can cause a range of symptoms, including abdominal pain, neurological issues, and developmental delays in children.
